School of Information Technology Bond University Trading in the Australian Stockmarket using Artificial Neural Networks by Bruce James Vanstone Submitted to Bond University in fulfillment of the requirements for the degree Doctor of Philosophy November 2005 Abstract This thesis focuses on training and testing neural networks for use within stockmarket trading systems. It creates and follows a well defined methodology for developing and benchmarking trading systems which contain neural networks. Four neural networks and consequently four trading systems are presented within this thesis. The neural networks are trained using all fundamental or all technical variables, and are trained on different segments of the Australian stockmarket, namely all ordinary shares, and the S&P/ASX200 constituents. Three of the four trading systems containing neural networks significantly outperform the respective buy-and-hold returns for their segments of the market, demonstrating that neural networks are suitable for inclusion in stockmarket trading systems. The fourth trading system performs poorly, and a number of reasons are proposed to explain the poor performance. It is significant, however, that the trading system development methodology defined in this thesis clearly exposes the potential failure when testing in-sample, long before the neural network would be used in real trading. Overall, this thesis concludes that neural networks are suitable for use within trading systems, and that trading systems developed using neural networks can be used to provide economically significant profits. i Statement of original authorship This thesis represents my own work and contains no material which has been previously submitted for a degree or diploma at this University or any other institution, except where due acknowledgement is made.

  • Technical Analysis: Technical Indicators
    Chapter 2.3 Technical Analysis: Technical Indicators 0 TECHNICAL ANALYSIS: TECHNICAL INDICATORS Charts always have a story to tell. However, from time to time those charts may be speaking a language you do not understand and you may need some help from an interpreter. Technical indicators are the interpreters of the Forex market. They look at price information and translate it into simple, easy-to-read signals that can help you determine when to buy and when to sell a currency pair. Technical indicators are based on mathematical equations that produce a value that is then plotted on your chart. For example, a moving average calculates the average price of a currency pair in the past and plots a point on your chart. As your currency chart moves forward, the moving average plots new points based on the updated price information it has. Ultimately, the moving average gives you a smooth indication of which direction the currency pair is moving. 1 2 Each technical indicator provides unique information. You will find you will naturally gravitate toward specific technical indicators based on your TRENDING INDICATORS trading personality, but it is important to become familiar with all of the Trending indicators, as their name suggests, identify and follow the trend technical indicators at your disposal. of a currency pair. Forex traders make most of their money when currency pairs are trending.

Applns. Madurai Kamaraj University, Madurai, India 2Associate Professor, Dept. of Comp. Applns, Madurai Kamaraj University, Madurai, India ABSTRACT: Predicting stock price movement is a highly challenging task as the nature of the stock prices are quite noisy, dynamic, complicated, non-parametric, chaotic and non-linear. The toughest job in stock market is to examine the financial time series data and make decisions which improve the investment returns and to minimize the loss incurred. Technical analysis is a trading tool that evaluates securities and attempts to forecast their future movement by analyzing price and volume data. Many traditional statistical tools are available for the investors for making decision in financial market. Many technical indicators such as Moving Averages (SMA, EMA, WMA, VWMA, DEMA), Trend Indictors (MACD, ADX, TDI, Aroon, VHF), Momentum indicators (Stochastic, RSI, SMI, WPR, CMO,CCI), Volatility indicators (BBands, ATR, Dochain Channel) and Volume indicators(OBV, MFI, CMF) are available to analyze the stock price movement. In this study, decision tree classification method is used to analyze the role of these technical indicators in predicting stock price movement of six high market capitalization companies of NSE. Keywords: Technical indicators, Decision tree analysis, ROC curve, AUC I.

The VIX Index is updated on a continuous basis and offers a picture of the expected market volatility in the S&P 500 during the next 30 days. The VIX Index was first introduced in 1993 and a second version was introduced in 2003 and is still in use today. VIX is also commonly known as the “fear index,” since volatility and the VIX index tend to rise during times that the S&P 500 is falling. Therefore, the VIX Index is said to measure the amount of fear or complacency in the market. Many analysts suggest that VIX is a predictive measure of market risk and future market action since this index is traded by some of the most professional traders in the world. However, there is also a large school of thought that suggests that VIX is a trailing indicator and so not suitable for attempts at market timing.

  • The SAVI Indicator
    The SAVI Indicator The JSE introduces a new “Fear Factor” Investor greed and fear play a significant and often irrational role in any financial market. These market sentiments can be seen in the volatility of the market – high volatility with large market moves suggest a fearful market while low volatility with little market movement indicates a lack of fear. How can investors measure this market sentiment and use this in their investment decisions? A volatility index or “fear gauge” is a reference number that can be used to indicate market risk at a glance. The first volatility index known as the VIX was developed by the Chicago Board Options Exchange in 1993 to measure the volatility of the S&P500. In 2007, the JSE launched the South African Volatility Index or SAVI to measure equity risk in South Africa; this was the first of its kind in an emerging economy. The SAVI is similar to the VIX, with the difference being that the US index measures implied volatility over one month, while the SAVI looks forward three months. The Ultimate "Fear Gauge" For Beating the Crowds to Big Profits It may be as cliché as it gets, but it's true. Investors are motivated by two things and two things only: Fear and Greed. It's just that simple. So more often than not, they turn quite bullish when they think a stock is headed higher and quite bearish when they fear that all is lost. The trouble with this strategy though, is that for most retail investors, it is exactly at these extremes in sentiment that they often lose their shirts.
